Hello everybody,
I am studying the rtcfg - stage2 configuration. When the stage2_file is larger
than MTU (1500) the file is cat to fragments which are sent to slave one after
another without any control of the file data transfer. I am having a problem
with that because the my rtnet slave can not process the data so fast. This is
why i am looking for some kind of flow control.
One option is the use of Acknowledge_Configuration frame and
Acknowledge_Length filed, which is sent by slave after it process one stage_2
configuration fragment. But this means that the stage2_file in length of 100
frames need 100 factorial (100*99*98*....*1) frames to be sent by master, which
is a huge number.
That is why i would like to add/change this part in the rtcfg source so that it
would enable fragment by fragment transmit of stage2 configuration file. What i
am not sure is what part of the code cuts the stage2_file and transmit it. I
went through the rtcfg.c and rtcfg_ioctl.c and i could not find where this
happens.
Can someone please give me some hint what files should i check/change or point
to workaround.
Best Regards
Klemen
